I have a Powerhouse Transceiver and an IR543AH. I only have the standard light dimmer modules. My old IR543AH worked fine with the Transceiver. With new 543, I have problems.

1. The 543 will not control any lamp modules anywhere in the house unless the Transceiver is unplugged.

Any ideas why my old 543 worked with the Transceiver and the new one doesn't?

2. Along with other lamp modules throughout the house, in my living room I have two modules on different circuits set to "A1".

Both modules work fine with the Transceiver.

When I unplug the Transceiver and use the 543 for control, one of the living room "A1" modules doesn't work. I've switched modules on that outlet and even switched the lamps, but it doesn't make any difference. I checked the polarity on the "offending" outlet, and it's fine. I changed the module in the "offending" outlet to house code B, but it didn't help either. Lamp plugged directly into the outlet works fine.

Do you think my new IR543AH is bad?

3. I should add that my Transceiver is also set to "A1". I wanted to change it to something else thinking that might help, but I don't have the instructions and can't remember how to do it.

Can somebody tell me how to do it?

Thanks in advance for any help!

P.S. I'm having problems with my TSU3000 controlling lights also, but I *hope* they are related to the above.
